Python/Django with REST Framework - Error on POST {"non_field_errors": ["Invalid data"]} -

i'm starting out django , rest framework , i'm getting error when trying post entity. there error is: {"non_field_errors": ["invalid data"]}. happens @ line serializer.is_valid()

this is view class looks like:

from django.http import httpresponse django.views.decorators.csrf import csrf_exempt rest_framework.renderers import jsonrenderer rest_framework.parsers import jsonparser api.models import payload api.serializers import payloadserializer api.services import payloadservice   class jsonresponse(httpresponse):     """     httpresponse renders content json.     """      def __init__(self, data, **kwargs):         content = jsonrenderer().render(data)         kwargs['content_type'] = 'application/json'         super(jsonresponse, self).__init__(content, **kwargs)       @csrf_exempt     def payload_list(request):           if request.method == 'post':              model = payload(code="754d", body="hello world")              serializer = payloadserializer(data=model)              if serializer.is_valid():                 serializer.save()                 return jsonresponse(serializer.data, status=201)     return jsonresponse(serializer.errors, status=400) 

here payload model reference:

from __future__ import unicode_literals sqlserver_ado.fields import bigautofield django.db import models   class payload(models.model):     id = bigautofield(db_column='id', primary_key=true) # field name made lowercase.     code = models.charfield(db_column='code', max_length=10) # field name made lowercase.     body = models.textfield(db_column='body') # field name made lowercase.     class meta:         managed = false         db_table = 'payload'

it's worth noting if set view , pass in json payload object part of request, works fine.

working json payload: {"code": "npmc", "body": "hello world"}

working view code:

if request.method == 'post':      data = jsonparser().parse(request)      serializer = payloadserializer(data=data)      if serializer.is_valid():         serializer.save()         return jsonresponse(serializer.data, status=201)     return jsonresponse(serializer.errors, status=400) 

response: {"id": 25, "code": "npmc", "body": "hello world"}

ok able find solution problem making use of djangos model_to_dict
